"Professor C. L. Weil planned the central heating, lighting and power plant. Murray and Ayres, of Saginaw, were the contractors for constructing the tunnel. The power hosue was built by Hoertz & Son, of Grand Rapids; Russel Wheel and Foundry Company, of Detroit, built the structural steel work, and the College men did the piping for the steam. The tunnel mostly six feet, six inches high, constructed of concrete, was 4100 feet long in all and cast 10$ for each running foot. The whole system cost about $140,000. The building which houses the equipment is located about one hundred feet south of the first veterinary laboratory . From this building, tunnels radiate to all the large buildings on the grounds."
"In the tunnels are placed the steam pipes for heating purposes, the electric wires, and the telephone wires. The smokestack is 125 feet high, 6 feet in diameter inside and 10 feet in external diameter at the base. It is built of v trifed hollow blocks. There are four 150 H.P. Scotch marine boilers equipped with the jones underfeed stokers. There are two 125 kilowatt dynamos. These are duplicates, either one of which is ample to carry the entire load. A smaller 45 kilowatt dynamo carries the day load." [1]
